Question

Can you help me solve this?​

Answer 1

Answer:

first one is rational, second is also rational, third is rational, fourth is rational, and fifth is irrational.

Step-by-step explanation:

Rational numbers are numbers that can be expressed as a fraction or part of a whole number. (examples: -7, 2/3, 3.75) Irrational numbers are numbers that cannot be expressed as a fraction or ratio of two integers. The reason why $\sqrt{12}$ is an irrational number is bc it's not a perfect square while$\sqrt{49}$ equals to 7 and is a perfect square.

Numbers given

6.(32)

• This is repeat non-terminating number which can be expressed as a fraction, so it is rational

3.121121112...

• this is non-repeat non-terminating number which can't be expressed as a fraction so it is irrational

√49 = 7

• This is rational

-27/4

• This is rational

√12 = 2√3

• This is not a perfect square and is irrational
